I just installed the UserManager package 3.0b5 on an i386 box..
I created the customer.
I brouse to the main screen and enter login.
I hit “login” and i get:
501/503 version not supported.
IE ver 7.0 5730.11
OOPS…

this is a bug, we have fixed but you must wait for a new package. we will see if we can update the current one.
UPDATE: the package is on the web. the name is the same, so just re-download it.
Cool !!
Im off to see the wizzard…
Craig
Ok…
I loaded the updated file.. 
I now see buttons on the left pane.. 
Now, try to remove a user… (Yes I checked the check box..)
It just says to select atleast one user… 
OOPS…
Please try again…
